G76 isn't terrible handy for a buttress thread being carved on a hard
maple stick

For a simple thread? I would just hand-code a G76.

I typically have gone to West Marine for epoxy. 5:1 mix ratio with

Modern epoxies like the ones sold by Total Boat set up harder and don't yellow
like the epoxies of the 1980's and earlier. An alternative to epoxies are the
hard urethane resins, also typically made with UV protection.
Total Boat looks like it's the #1 brand of epoxy used by people making those

I won't promise it does. It's been a while since I last played with it. Even
if it doesn't, it may be possible to pretend you are machining a slot in the
X-Z plane and use that for a lathe profile.

Other options for buttress. DIN | ANSI .. Either grind a tool out of M2 or
equivalent or go shopping for inserts on the web surplus sites. They won't be
cheap but a bit less hassle.
Single point thread mill??
Lathe sound easier than milling it.

That much stock tilt (30 degrees) in a 21" workpieces length, is well
beyond the z travel available on that gantry mill, not

Freecad "path" workbench generates g-code toolpaths. You can paste your
openscad source code into freecad with the openscad workbench.

Single point thread mill
First off this is a really simple design. I think it could be done on a
normal manual lathe with no CNC. Just use the correct thread cutting gears
to drive the carriage.
The trouble is that writing g-code by hand or turning handwhels with no
computer breaks the chain that goes from your design

If you can
If you can tilt the head at an angle, then something as simple as "G1
X300.00 B30.00" will do it, depending on how you have configured the B
axis. If you can't tilt the head, no amount of GCODE will help you.
I'd just do it on the lathe ...
